This. Is. Awesome. I love the lighting on this guy, and that is one goddamn fearsome maw.
However, its scale seems to get confused for me. Between the size of that huge... portal/light source and the focused orange spot in the background, I keep interpreting this scene as being set in the bottom of a tiger trap. I'm just offering that because it makes the ship seem more like a toy, and the monster a little less scary. SUPERB work overall, sir. Good luck with this contest, I so love your monsters!
